An upper supporting seat 20 is an upward protruded cambered sheet. Each of two opposite sides of the upper supporting seat 20 has a penetrating portion 22 which is penetrated by a threaded hole 23. The two penetrating portions 22 are symmetrical. Each upper surface of the two opposite sides has a respective slot 24 at a center portion of the side. A lower side of the upper supporting seat 20 has a plurality of buckling teeth 46. A lateral side of the upper supporting seat 20 is formed as an indication portion 28 adjacent to the buckling teeth 46 for indicating angle.

A lower supporting seat 30 is installed at a top of a standing tube 10. The lower supporting seat 30 is a downward cambered sheet. Each of the two sides of the lower supporting seat 30 are installed with a convex portion 32 corresponding to the slot 24 of the upper supporting seat 20. Each convex portion 32 has a via hole 34. Each of the via hole 34 and a corresponding one of the threaded holes 23 of the penetrating portions 22 of the upper supporting seat 20 is passed by an adjusting stud 36. Thus, the upper supporting seat 20 and the lower supporting seat 30 are combined as a supporting device.

An upper clamping sheet 40 has an upward cambered upper portion. Two side of the upper clamping sheet 40 are formed with two sheet-like structures. The arc of the upward cambered upper portion of the upper clamping sheet 40 is similar to the arc of the lower side of the upper supporting seat 20. The upward cambered upper portion of the upper clamping sheet 40 has engaging teeth 46. Each of two ends of the uppermost tooth of the engaging teeth 46 has a rib 48. The engaging teeth 46 is engageable to the buckling teeth 26 of the upper supporting seat 20. Each of two sides of each sheet at the two sides of the upper clamping sheet 40 is formed with an ear 42. A lower side of each ear 42 is formed with a recess 44 which is formed as a first clamping portion 44.

A lower clamping sheet 50 has a downward cambered groove 56 at a center portion thereof Each of two side of the lower clamping sheet 50 is formed with a sheet which is corresponding to the sheet of the upper clamping sheet 40. By the combinations of the sheets of the upper clamping sheet 40 and lower clamping sheet 50, the upper clamping sheet 40 and lower clamping sheet 50 are combined as a clamping structure.

A lower side of the lower clamping sheet 50 corresponding to the cambered groove 46 is a downward cambered structure which is matched to the downward cambered structure of the lower supporting seat 30 so that the lower clamping sheet 50 can resist against the lower supporting seat 30 without sliding out. Each of two ends of each sheet at two sides of the lower clamping sheet 50 has an ear 52. The two ears 52 of the same sheet of the lower clamping sheet 50 are symmetrical. An upper side of each ear of the lower clamping sheet 50 is formed as a trench which is as a second clamping portion 54.

Referring to FIGS. 2 and 3, the assembly views of the present invention are illustrated. In assembly, the first clamping portion 44 and the second clamping portion 54 at the same side are coupled as a receiving space. A rod 60 passes through the receiving space. Thus, totally, there are two rods 60 passing through the receiving spaces at two sides of the present invention. The upper clamping sheet 40 and lower clamping sheet 50 are coupled and then they are received in a space between the upper supporting seat 20 and the lower supporting seat 30. The upper supporting seat 20 and lower supporting seat 30 are engaged by passing the adjusting studs 36 through the via holes 34 of the lower supporting seat 30 and threaded holes 23 of the penetrating portion 22 of the upper supporting seat 20. After assembly, the assembly view is illustrated in FIG. 2.

The spacing of two ribs 48 at the uppermost teeth of the engaging teeth 46 serves to receive the upper supporting seat 20. When the upper supporting seat 20 is screwed to the lower supporting seat 30 by adjusting studs 36, the ribs 48 have the function of stopping for preventing the change of the engaging angle 62 so that the upper supporting seat 20 is firmly secured to the upper clamping sheet 40. A further function of the ribs is to be as an indicator as the orientation of the cushion of a bicycle is adjusted. When the orientation of the upper supporting seat 20 is adjusted with respect to the upper clamping sheet 40, the ribs 48 are helpful to the identification of the orientation.

A middle side of the indication portion 28 has an indication of 0. Indications of 15 degrees and 30 degrees are indicated at two sides of the indication portion 28. One lateral side of the engaging teeth 46 is indicated with an arrow 47. When the orientation of the cushion is adjusted, by the indication of the arrow 47, users can know the orientation of the cushion. Thereby the user can identify the effect of adjustment.

When the user desires to adjust the orientation, the adjusting studs 36 passing through the upper supporting seat 20 and lower supporting seat 30 are released firstly so that a larger space is formed therebetween. When the upper clamping sheet 40 and lower clamping sheet 50 are shifted to a desired orientation by the assistance of the indication portion 28 and the arrow 47. Referring to FIGS. 4 and 5, when the desired orientation is acquired, the adjusting studs 36 are screwed to combine the upper supporting seat 20 and lower supporting seat 30 so as to complete the adjusting work.

In the indicating device of a bicycle standing tube of the present invention, when the user adjusts the orientation, by the indication from the indication portion 28 of the upper supporting seat 20 and the arrow 47 of the upper clamping sheet 40, the engaging teeth 46 can be engaged to the buckling teeth 26 rapidly.
